#### Tóm tắt

*Radiation properties of a dielectric-wedge antenna fed by a dielectric slab waveguide of the same material is accurately analyzed by using new boundary integral equations that are called guided-mode extracted integral equations. The derived boundary integral equations in this paper can be solved numerically by using the boundary-element method. Computer simulation results are confirmed by the use of energy conservation law. Typical results of reflected and scattered powers, as well as radiation patterns are presented. With certain conditions, it is shown that almost 100% of incident power is radiated*
